Add barcode encoding support

- Add new barcodeencoding field to database
- Read barcode encoding from pkpass file
- Add barcodeencoding to import/export
- Add barcodeencoding to share URI
- On default, use zxing's GuessEncoding function in StringUtils (this
  should not use UTF-8 unless needed)
- Allow manually forcing ISO-8859-1 or UTF-8

+VectorDrawable does not support all SVG features, such as shadows and masks.
+Therefore the ic_launcher files are slightly different from the master files: no shadows, minor color tweaks, path optimisation.
+Use ic_launcher_*.svg files to generate assets for the app icon
+Use master_*.svg files to generate other assets (e.g. feature graphic, playstore icon) or to rework the icon design

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+catima.g9ex3@hackerchick.me.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

 ## Code Changes
 
+Note: submitting LLM ("AI") generated code is strongly discouraged, as such
+code is often (subtly) incorrect or overcomplicated (for example: unnecessarily
+pulling in extra libraries for functionality already covered by existing
+libraries). It also often makes unrelated changes that increase the risk of
+introducing new issues and complicates reviewing. Even when it doesn't do any
+of the before mentioned things, it will often not fit the coding style and flow
+of existing code, requiring excessive refactoring.
+
+While we cannot ever control or be sure if LLMs were used to generate the
+submitted code, it is your responsibility to ensure that whatever code you
+submit is correct and fits within the design of existing code. It is never
+acceptable to defend a change by stating a LLM suggested it.
+
+This is a personal plea more than anything: please understand that writing code
+is the easy part. The hard part is making sure the code fits the design of the
+rest of the application and is maintainable. Reviewing is a very time-consuming
+task for this reason. Please do not use LLMs to quickly generate a "fix" and
+moving the cost of labor to me as a reviewer. If you do use LLMs to generate
+part of your code, please be open about this, explain what was generated how
+and how you confirmed and refactored the code to fit the project and minimized
+risk.
+
+Please never submit LLM-generated code as-is.

 # Privacy Policy
 Catima does not collect or transmit any personal information.
@@ -11,6 +11,12 @@ To ensure correct app functionality, we require access to the following:
 
 Catima offers a feature to share cards with other users. All the relevant data is in the generated shareable URLs and never transmitted to our servers. When viewed through catima.app, the data in the URL is rendered using client-side Javascript to further ensure no data is ever transmitted to us.
 
+## Crash reporting privacy
+
+In the FOSS version of Catima (the version used on IzzyOnDroid, F-Droid and GitHub), the open source crash reporter ACRA is used for crash reporting. When a crash is detected, Catima will ask the user if they are willing to report the crash. If they choose to do so, the user's mail client is opened so they can review the data that would be sent. Crash reporting data is only sent when the user explicitly chooses to do so, it is **never** sent automatically. Crash reporting data is only used to solve crashes and no (potentially) sensitive information is ever shared. Users who do not want to be asked to report crashes can disable the "Ask to send crash reports" setting in Catima settings.
+
+For the Google Play version of Catima, crash reporting is [managed by Google](https://support.google.com/googleplay/android-developer/answer/9859174?hl=en). Users can opt in or out of crash reporting through the Google app under the "Usage and diagnostics" setting.
+
 # Changes
 This Privacy Policy may be updated from time to time for any reason. We will notify you of any changes to our Privacy Policy by posting the new Privacy Policy to https://catima.app/privacy-policy/. A snapshot of the Privacy Policy is available within the Catima app, though it may be outdated. When the Privacy Policy on the website and in the app differ, the website should be considered leading. You are advised to consult the Privacy Policy regularly for any changes, as continued use is deemed approval of all changes.
